The set will come on for a few seconds then I hear a click and there will be no power. I can unplug the set for several hours and it will power on like normal, but after a time or two of turning it on and off it will go back to giving me the click and no power. Is this something I can fix myself by buying a new part and installing it? Is there a relay that can be replaced or is this a sign of needing a whole new power supply?

Hi there, Check IC601, C603 for leakage, I601 and vertical pulse detector QN05 for poor convergence check RK42 for open circuit. Best regards, Arpi

The fact that you're getting any action from the primary or secondary relays points to an open short in one or more circuits or a short to ground in one of the Hv load circuits and the S/D circuit is simply shutting the set off in protect mode... We see that a lot with PTV's when the convergence is fouled or the HOT or FBT is shorted or something along those lines.
I will Pando the service manual if you drop me a post to my addy specifying exactly what you need. If I remember correctly the manual for this one is actually a UWX20B with a supplemental.

If you can solder you can Fix It STK ICs they are big black ICs will have part number on them example STK392-110 replace Both and these resistors RK42 3.3ohms RK46 1.8 RK5 2.7 RK54 1.5 RK58 3.9 RK60 2.2ohms upgrade to STK392-150s better ICs
Testimonial: "Quick and thorough response! Thanks!"
SOURCE: hitachi 50ux19k model that will power on and powers right off.
Replace Both of your STK ICs that will fix this they are big black ICs will have part number on them STK392-110 use 180s Mats Electronics has them 1-800-628-1118
